ABSTRACT The experiment was conducted during the successive seasons of The aim of this experiment was to study the effect of fertilizer doses , types and application methods on the grain yield of wheat (Triticum aestivum L .) . Experimental method is a split - split plot trial with four replications . The main plot was composed of tow methods of fertilizer application (broadcasting and localized placement) in randomized complete block design . Subplots consisted of tow types of compound fertilizers (Urea + Triple super phosphate) and Nitrophoska . Sub - subplots consisted of four doses of each fertilizer . Yield components of wheat which were investigated in this study included number of grains per spike , thousand grains weight , spike index , grain yield and harvest index . In this study the general trend was that the increase in fertilizer dose highly significant increased number of grains per spike in the second season , grain yield in both seasons , but there were no significant difference in thousand grains weight and spike index which were not affected . The results showed that the fertilizer doses significantly decreased harvest index . Generally the results show that there were no significant differences in yield components between the fertilizer types and between the application methods .
